.To a/ZZ whom t may comerm- Be it known that 1, FREDERICK P. RosnAcK, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Book-Stapling Machines, of which the following is a specification.

My invention relates to that class of machines employed in binding books by means of staples formed from wire which is fed into mechanism, which severs the Wire, forms the stapledrives the 'saine into the work and thereinafter clinches the staple.

The mcreimportant objects of my ment are to provide a wire stapling which is capable of having all of simultaneously and relatively adjusted by means of one controllingdevice, in such a wayI that the same may be adjusted to staple different thicknesses of work; and thejlength of the staple formed, the distance the same is driven, dsc., all he relatively' and proportion.-

improvemachine, its parts tion secured in the working thereof, than is possiioie in machines, the diiferent parts of which must be independently adjusted.

Further objects are to nprovide a wire straightening device and a reciprocating cut- ,o mechanism which will provide an` unbroken path orcontinnous conduit for the wire while thereafter and before severing the same, will be removed a distance from the block around which -the staple is formed, equal to the length of limb the staple is desired to have, and to provide a wire stapiing machine generally improved in all its working parts.

My improved machine is fully illustrated in the accompanying drawings, in w hich:-Figure 1 is a front eievation of myimproved machine; Fig. 2,a side elevation representing the right hand side of the Fig. 3, a broken sectional view of the same; F-ig. 4, an enlarged broken sectional view of the clutch portion of 5, a plan view of the clutch dog;.vFig. 6, a cross-sectional view on line 6 of Fig. ,viewed in the direction of the arrow; Fig. 7,`a" sectional view in line 7 of Fig. et, viewed in the direction of the arrow; Fig. 8, a sectional view-on line 8 of Fig. 4, viewed in the arrow; Fig. 9, aside view of therdog-releasing device, or stop; Fig. 10, a plan'view of the same; Fig. 1l,a plan view of the table with its guide attachments; 12,a`plan view of the saddle, with the portieri illustrated in Fig. 1l, removed; Fig. 13, an edge view ot the table portion of the saddle as indicated by dotted lines 13 in Fig. 2; Fig. 14, an enlarged front elevation of that portion of. the machine containing the staple clinching pawls dan., and over the end of which the saddle or table is placed; Fig. 15, a planiew f the staple clinciiers and case shown in Fig. 14; Fig. 1G, a broken front ele vation of the upper portion of Fig. showing the staple clinching pawls and the operat` ingplunger or slide; l?, an enlarged perspective view of one of the staple ciiuching pawls; Fig. 18, an enlarged front elevation of the head portion of the machine with the tace plate, former, driver and feed portion of the machine removed.

The entire mechanism comprised in n1y n1a `l chine may be supported in any suitable inan-4 ner, but the form of support I have found;

mostdesirable is the one illustrated in the accompanyingdrawings, which consists of a. holf low metal standard A (Fig. l), invol vinga vertical portion z arising from an expanded hol.- low base z; and terminating at the upper end in anenlargiig portion .e2 (Fig. 2), extending atan augleo -about forty-tive degrees, from a vertical portion z and terminating in an opening cut on a vertical `plane and also in an opening cnt ona horizontal plane; and involving also a branching portion zsextending from the vertical portion z, at a similar angle with,

and immediately beneath, the inclined portion e2.

in Figs. 4 and 8, for the reception of the dog t, illustrated in Figs. 4, 5, 6 and 7. One sur- .face of each of the cuneitorm recesses u (the backward one as .the hub revolves in the direction indicated by the arrow in Fig. 8), is

made parallel with the hub B2 and shaft B.

The dog tis provided with an extremity or nose t* to accurately [it into` the cuneiform recesses u, and is made to operate freely within the adjacent spaces t and t2 provided therefor in the collar and shaft B, shown in Figs. 4, 6 and 7, and is further provided with a coiled spring t3 which operates against the `pin :1:4 within the collar a," as shown in Fig. 4. Thus a form of clutch is provided, whereby. when the vdog t is in its normal position its nose t will intrude one of the euneiform reeesses u in the inner end of the hub B2'and the rotarygshaft B will be turned by the belt pulley-B when the latter is revolved in the thedrection .indicated by the arrow in-Fig. 8; but when the belt pulleyB is revolved-in the opposite direction to .that indicated by the'arrow inF-ig; 8 the extremity #of the dog t will .beforeed out ofthe cnneit'orm recess u.

and the revolution of thebelt pulley B will not cause the rotary shaft B to turn.' The dog t, as'vwill lise seen'in Figs. 4 and 5, is'providedwith .a nose 5, similar tothe nose t4, :madefby cutting-away a portion of the bac-k;

which will be 'seas-ee s when the latter will, by the action of the coil spring t3, be thrown forward till the nose t4 will engage with one of the cuneiform recesses u in the hub B2 of the belt pulleyB, forming a clutch as aforesaid and causing the rotary shaft B to be revolved and the machinery thereto attached operated in the manuel' hereinafter described. The inner end of the rotary shaft B is, by the cog wheels D and D2,

bevel geared to the cam D, as shown in Figs. 3, 32 and 33. The bevel cog D is provided with an elongated hub r fitted loosely within the cani D, but within which it is prevented from turning by means of the loosely fitting key or feather r', while at the same time the cam D will be allowed to reciprocate upon the elongated hub r, for the purpose hereinafter set forth. The bevel cog D2 and cam D are iitted loosely over the perpendicular rod XV around which they together revolve and more particularly described hereinafter. Y

In the periphery of the cam D are cut grooves q, q and q2 for actuating the former K, the driver I and detail N, as will be made more fully hereinafter to appear.

To the right and left sides of the rectangular opening in the front of the portion z2 of the hollow metal support A are fastened guides G and G', asshown in' Figs. 18 and 25, the purpose of which guides is to hold in .pcf sition the bed-plate H and the parts thereto attached. of the rear of which is shown inFig. 3dr-has a general rectangular shape, with an opening somewhat shorterand narrower than the opening in the front of the portion z2 of the hollow metal support A,and is provided with lateral guide flanges h and h distendingsuilciently to be prevented from aforward displacement by engaging with the guides G and G.

I is a rectangular plate, which I denominate the driver head. It is provided with a central rectangular opening (seen in Fig. 19) and is flanged laterally, as shown at 'i and z" in Fig. 25, and lits into and between the flanges zv and h of the bed-plate H in a rect? angular recess there provided for its reciprocation. To the upper end of the driver head I is fixed a spindle I2 hearing an anti-friction roller i3 which is made to intrude the groove q of the cam .D (shown in situ in Fig. 33). To the outer surface and lower end of the driver head I (accurately shown in Figs. 19, 33 &c.,) is attached thedriver I by means of the pin ll. l The driver I is provided with lateral flanges p and p', Figs. 19, 42 and 44, adapted to intrude grooves hereinafter-to be described. The driver l is provided at its lower end with a lip l (Figs. 33, 35, 36, 37, 38 and 4l) for the purpose hereinafter set forth.

K, Figs. 19, 25, 33, dsc., is a reetanguar bar which, because of its function in forming the 'wire into staples, I denominate the former.

rllhe former K is made of sufficient width to fit snugly into a groove prepared for its refzeption ,and reciprocation, eentrallyand verpaths in which made to appear.

The bed-plate I-I-a separate View 1 tically along the face of the driver head I between the flanges z' and i." thereof, as seen in Figs. 25 and 33. To the back and near the longitudinal center of the former K is fixed a spindle K bearing the anti-friction roller K2 (Figs, 19 and 33.) which spindle is of such alength that it'will pass through the rectangular opening in the driver head I and intrude the groove q in the cam D (Figs. 18, 31, 32 and 33). Into the rear surface of the former K, and below the spindle K', is cut a groove 0, which is of somewhat less width than the former K, leaving marginal edges o and 02 (accurately shown'in Figs. 4l, 42 and 43); into the interior surfaces of which margi- Y ual edges o and ozare cut longitudinal grooves o3 and o, the function of which is to provide the flanges p and p of the driver I may reciprocate (see Figs. 19, 33, 39, 42 &c.); as will hereinafter more fully be At the lower end of the former K, and for the distance of somewhat morethan an inch, the aforesaid groove o is cut entirely through from the back to the front of the former K leaving side bars rz and n', one on each side ot' such opening as will be seen in Figs. 33, 412, 43, 45, dac.

Between the side bars n and u is hinged the device L, shown in Figs. 33, 35, 36, 37 and 39; which, because of its lending support to the wire while the staple is being formed e., l denominate the inclined support. On the innersurfacc of the inclined support is a ledge L2. To the front of the former K and above the inclined support L, is fixed the upper end of the flat spring I. (Figs.33,` 35 and 36) with a tension causing the lower end to bear against the inclined support L for the purpose hereinafter shown,

Centrally located in the lower part of the bed-plate Il is the device M (Figs. 33, 35, 36, 37 and 46) which from the nature of its purpose is termed the anvil block. The anvil block is provided with a nose m, made to fit between the side bars n and n of the former K; a mouth m suiiciently mit any size of wire desired for making staples; hinged nippers m2 (Rigid) operating against a coil spring mi; a shank m4 sufciently long to pass entirely through the bed-plate Il; and a coil spring m5 operating to throw the anvil block M forward from the aperture m6 in the bed-plate Hand into which aperture the anvil block maybe made to recede.

Centrally located on the lower end of the bed-plate ll, and vertically placed immediatcly above the anvil block M is the detail N, Figs. 18, 33, 47 etc. The detail N is a metal bar bent backward at the upper extremity l1 to form a shank of suflicient length to pass through the opening in the bed-plate H and engage the groove q2 on the lower edge of the lcam D; (Figs. 3l, 33 &c.,) terminating at the lower extremity in the provided with slots 1l2 the screws 1l4 and 1l5 flat spring 11'; and

On the inner surface of the sleeve O is at-ji "tached the anti-friction roller k by means-off the pin laf so as to engagewitlithe cam D in the groove q whereby a reciprocating move-- ment will be communicated vto the said sleeve O by theA revolution of the said cam D. On the left side of the sleeve O is attached an ear O', which protrudes beyond-'the portion z2 of the hollow metal support A- through a slot there provided `'for the same, as shown in- Figs. 18 25 and 32. Onthe left side of the' portion z2 of the hollow metal sppport A, and

In a groove in the lo,w er part of ythe -face .19,A26,'27, 28, 2Q and 30) consists of va rectany guiar cut-oi block c, in a circular opening of Fig. 2G). The cut-ott longer than the cut-off block c and, as shown Figs. 2S, 2!) and 30, is internallyfitted with a fixed core c3 in such a maniieras to guide the wire, used in making staples, through a small orifice c* near the circumference of the cutoff tube c; the cut-offtnbe c' together with the core'c3 thereby forming a sort of funnel to guide the wire into the mouth of the anvil block M in the manner hereinafter more particularly set forth.` p

Ou the circumference of the cut-ott tube c', and near the orifice cL1 is fixed the lug c5. ln the side of the cut-off block c, and, penetrating to the circular opening provided for the cutollf tube e, is a segmental opening c Figs. 19 and 3U through which the lug rf of the eut-oft' l tube c may protrude.

It will be seen that when illecito-ofi" tube c is inserted through the opening therefor pro vided throughout the cut-oft block c, in such a manner that the lug e5 of the cut-ot tube c will be in thc segmental opening c off block c, and the knife c2 thereafter fas tened against the end of the cut-off =block c, the cut-oli? tube c will be confined within the cut-off block c while the lug c5 protruding from the segmental opening c provides a.

means by which the cut-off caused to revolve part of a extent of the segmental the cut-off block c. i i

To the same side of the cut-oit block c through which the segmental openinge6 is made, but at the other extremity thereof (Figs. 19 and 30) is fixed the pin c7, the purpose of which is to engage with the slot d5 of the arm S2 whereby a horizontal movement may be given to the whole cut-off mechanism for the purpose hereinafter shown.

V, in Fig. 18 is au L-shaped cut-oil.v bar which is capable of an upright reciprocating movement in a groove therefor provided .in the bed-plate H of the machine. Longitudinally throughout the face of the shorter arm of the L-shaped cut-ot bar V is cnt agroove l) (Figs. 18 and 2(3) large enough to receive the lug ci'l of the cut-o` tube c. Y To the rear surface of the cut-olf bar V, and near the upper extremity thereof is fixed` the spindle b carrying the anti-friction rollei' b2v (Figs. 26 and 27), in such a position as to be in the pathof the small cam D3, when thelatter is moved-in the direction of the liition pf'the cam D, on the circumference of which the said cam D3 isi attached. On the rear surface of the cut-ott, bar V and at adietance below the spindle b' and the anti-fric:- tion roller b2 is fixed a pin b3. Immediately behind the cut-oit bar V and in the lower portion of the bed-plate l'I, in a perpendicular groove there provided (Fig. 26) is a-coil spring V', which engageswii l,the pin h3 of the cut-- olf bar V with a tension downward. From thc above description it will be seen that tube c may be revolution-the opening c"-within levery revolution of the cam D will cause the cam D3 to engage the anti-friction roller b2 on tube c' is somewhat' ofthe cut.

described. -when the perpendicular arrow point, by the rev,o`

the spindle h whereby the cut-oil2 bar V will be raised, the lug c5 of the cut-ott' tube c', being in the groove Z?, will be thereby lifted, whereby the cut-oit tube c will be turned within the cut-ol block c, when the wire, if protrudingl from the orifice c4 ot' said cut-od tube, will be borne against the knife (seen 1n Fig. 26) and therebysevered; and that immediately after the cam yl)3 has passed from bcneath the anti-friction roller Zi'e all the parts will, by the tension of the coil spring be returned to their normal position.

Upon the perpendicular rod W' on which the cam D and bevel cog D2 revolve, is lixed collars a and a (shown in Figs. 32 and 3'3.) which prevent the cani D from reciprocating thereon and as will be seen, particularly in Fig. 33, portions of the bed-plate H bear against both the upper and lower ends ot' the cam D, so that while the latter is permitted to revolve therein any vertical displacement of 4the cani D' will cause a corresponding d isplacement of the bed-plate H together with all therparts thereto attached.

Beneath the portion z2 of the hollow metal support A, and behind the vertical opening in frnt. of which the bed-plate H and the face plate S with their attendant parts are placed, is fastened-by means of screws or bolts-the stirrup W (Figs. 32 and 33). This -stiriup W is formed into a nut through which the screw eutI on the lower extremity ofthe perpendicular rod W operates. The upper extremity of the perpendicular rod W passes through the cup e" of the hollow metal support A, and extends beyond the thickened portion thereof made to provide a steadier bearing therefor, and has fixedto its extrem; ity the, hand wheel W2. AThe bevel cog vD- (Fig. &c.,) rests upon the stirrup WWhile its elongated hub r passes upward through the part .z2 of thehollow metal support A and enters the camD in the-manner hereinbefore It will now be understood that rod 'YV is, by means of the hand wheel W2, screwed into or out of the stirrup W', the cam D, the bed-platell and all the attached mechanism will be .lowered or raised thereby-the cam D reciprou eatingl upon the elongated hub r of the bevel cog D2, yet being prevented from turning thereon by the key or feather r' as hereinbefore described. i

0n the right hand edge of the face plate S, as shown in Figs. 1 and 2, is fastened a small inverted bracket br, with a thickness sufficient to extend somewhat ward edge ot' the part z2 of the metal A; and on such portion ot the metal A, below the inverted bracket bracket hr of the same size; which together will forni a gage for adjusting the machine to the thickness of the work desired to be stapled; lfor as the face plate S, the bed-plate I1 and all the parts thereon dependent are, together with the cam D, raised and lowered by-t'urning support Support br, is fixed the over the for ICO the hand Wheel Winsomuch will the distance between the extended arms of the inverted bracket br and the bracket br beincreased or decreased-this distance being equal to the nearest approach of the driver I. to the table or saddle supporting the work to be stapled. The hand wheel XV and mechanism thereby controlled is held in adjustment by means of the spring stop VW (Figs. 1 and 2) which engages with the corrugations on the circumference of the hand wheel W2. It will now be also understood, by reference to Figs. 18 and 19, that as the face plate S &c., is raised in the manner above described, the disk g of the feed arm T will, in consequence thereof, be raised and the finger Q vwill be thereby made to take a position in the groove g2 nearer the center of such disk and as a result thereof agiven oscillation of the linger` Q will thereafter give a greater movement to the feed arm T, which will canse a greater length of wire to be fed into the machine, to. be cnt olf and formed into staples with longer limbs suitable to the work of such increased thickness, and that a reverse movement of the Vface plate will have an opposite eect.

The lower extremity of the plunger. actuating rod 4U hereinbefore (Fig. 3)'. referred to, is'` pivoted to the plunger leverfn2 withinthe standard le' 'of the hollow metal. support A. The plunger lever v2 is fulcrumed at U3 (Figs. 2 and 3) and projects forward through and be youd the branching portion z3 of the hollow metal support A. To the outer extremity of 16, and`17). The V-shapcd pawls aa and 0.a.

the plunger lever v2 is pivotallyaffixed the plunger X (Figs. 1, 2, 3, 14, 16, &c.,) in such a position that it will rise immediately under the driver I dsc., which reciprocates vertically inthe bed-plate Il tbc., hereinbefore described.

Fastened to the front of the branching portion z3 of the hollow metal support A, and in such a manner that the saine will be lnmediately under the driver I. dsc., is the clinching device shown in Figs. 1, 2, i4, 15 16, &c., which consists of a double plate X rigidly and perpendicularly fastened tothepart z3 of the hollow metal support A; the adjacent surfaces of which double plates X are so grooved as to permit the plunger X to reciprocate ver tically therein; such grooves being slightly widened in the upper portion thereof to admit the V-shaped. pawls aaand aa (Figs. 15,

are each pivoted at its apex near the edge of such groove and near the upper extremity of the double plate X. lach of thelipatvls aa and aa is grooved in its uppersurface; which grooves converge toward the free end.- (Figs. `15 and 17.) The upper extremity of the plunger X is provided with a T-shaped head aa, the opposite extremities of which head engage` with the Vshaped pawls aa and aa asaccurately shown in Fig. 16. It will now be understood that insomnch as the staple'clinching device is im mediatelybenea th the tormcr K, the driver I tbc., the points o. the staples when driven, will be driven into the grooves on the upper edges of the V-shaped pawls aa and aa'; that if this is done when the plunger X is down the points of the staples will invariably be bent toward each other; and that if the plunger X be then forced upward the clinch of the staple will be perfected as shown in Fig. Sil-ws being thegwire staple.

Within the groove :r3 on the rotary shatt (Figs. 2, 3 and fl) is fixed in the cam v4 (Flg. 6). It will be seen that at each revolution of the rotary shaftl B this camp:4 will engage with the anti-friction roller'in the head v of the plunger actuating rod o, pushing the same downward, when, by the movement of rthe plunger lever v2, the plunger X will be made to rise in the groove between the vertical double plateXrwhereby the'V haped pawls 'aa and aa will'beiorced against the staple theretofore ydriven, perfectly clinching the same as above.

To insure the perfect working of the plunger actuati'ngfrod u &c., a coil spring 115 (Figs. 3 and l) is employed,'linkingthe plunger lever u2 to the branching portion of the hol low metal support A the tension of which coil spring 1151s to cause the plunger rod tb bear upward, thrusting theanti-friction roller in the uppe'l` extremity against the camu4 on the rotary shaft B.

To each side of the front of the branching portion a of lthe metal support A is rigidly fastened a saddle bracket Y and Y( (Figs. 1 and 2). These saddle brackets are made in the shape of the frustum o f awedge with the converging faces at a-rightapgle each to each, and each at fortyve degrees fri'ria perpendicular: theA upperV base of the frust um is therefbre horizontal.y

Z and Z (Figs. 2, 1l, 12 'and' 13) are thin metallic plates of any desired size iixed at a right angle each to each by` means of angle irons llb and bb. The angle irons bb and bb are so disposed on the under surfaces of the plates lZ and Z' that, by means of the wing, nutsr blt2 and bb3 (Figs. 2 and` 13) they may be rigidly fastened to the saddle brackets Y and Y'. I

At'the angle plates yZ and Z', andigetwee'n` the anglo irons bb and bb is an -aperfiiierbbjradapted to permit the penetration' of the `perpendicular donbe plate X', as shown in Figs. 1 and 2. Nearl the lower edge'o'f the plate Z, also between the angTe"irons-'lslb andlbbf, is a 'Slinilar aperture bbi forma like purpose.

Iby the plates Z and Z', a's shown in Fig. 2, may, by loosening the wing-mits bbIz and bbs,

the position indicated b the dotted lines 13 Fig. il, when the wing nn. bb,2 will take the por sition of the dotted indication thereof Aandcan be there secured. The upperi extremity of the perpendicular double plate X will then protrude from thel aperture b!)5 (Fig. 1l) in the lplate Z.

In Fig. 1l, cc and 0c' aro adjustable guides u into the groove :1:3 andv formed by the unio'n :of theI IIO It will be understood that the saddle formed be made to serve as atable by placing it in f to aid in properly placing the work to'be stapled when the plate Z is used as a table.

In Fig. l, t is an adjustable table or tray hinged to the hollow metal support A, and provided with a standard sf, which table is an auxiliary to my machine and constitutes no part of my invention.

In Figs. 25, 2 and l, ty is a tra-y which I have bracketed to the rear of the part z2 of .the hollow metal support A, as a convenient receptacle for tools dac., and not as an element of my invention.

My machine is operated as followsz-lf the work to be stapled has been folded and is to be secured in the fold, the angularlyattached plates Z and Z brackets Y and Y as a saddleybut it' the work has not been folded, the attached plates are placed as a table and the guides cc and cc adjusted as desired. By means of the hand wheel W2, the face plate S together with the bed-plate H, the cam D, and all the corelative parts are simultaneously adjusted according to the thickness of the work to be stapled4 as gaged by the inverted bracket hr on the edge of the face plate S and the bracket br on the side of the part a2 ofthe hollow metal support A, (Figs. l and 2.) The belt pulley B", revolvingin `the direction indicated by the arrow in Fig. 8, the shaft B will be caused to turn by pressing the pedal C, which will draw the stop w at the upper extremity of the vertical shaftrrw downward releasing the nose t5 of the dog of the coil spring t3, the nose t* will be thrust forward into one of the cuneiform recesses u in the end of the hub B2y of the said belt pulley Bf whereby a clutch vis formed as hereinbefore described; and the turning of the pulley B will cause the vrotary shaft B to revolve; the rotary shaft B will turn the bevel cogD thereto attached; the turning of the bevel cog` D. will turn the bevel cogD2 geared thereto; the turning ofthe bevel cog D2 (the t, when, by the 'action prolonged hub'rthereof being prevented from turning within the cam) D by the feather r) will cause the revolution of the cam D in the direction indicated byfthe arrow in Fig. 31. BecauseY of the position of the anti-friction roller c on the spindle r/,on theinner sur face of the sleeve O, in the groove g of the cam D,-the initial movement being npward-the motion being communicated tothe crank Q by the ear o on the sleeve O and the link R (Figs. 18 and 32) the finger .Q will be moved horizontally outward. The finger Q,`

being in -the groove g2 of the disk g of the feed arm T (the face plate S and parts thereto attached, Fig. 19, being secure-din their proper placesvin the bed-plate '13) such outward movement of the finger Q- will cause the disk g to turn on the pin g `whereby the vlower extremity g3 of the feed arm T will be thrown inward and the wire ww fed into the machine by the automatic clutch thereon and hereinbefore described. .Because of the space bet-Ween the points d2 and d3 of the are secured upon the saddle Y-shaped upper extremity of the cut-off arm S2 there is considerable movement made by the lug g4 on the said disk g before the said lug g4 engages with the said point d3 and thereafter causing the said cut oif arm S2 to bemoved about the fulcrum d and the lower consequent outward movement of the. other extremity thereof will draw the cut-0E lblock c duc., away from the 'anvii block M aforesaid a sucient distance that the length of wire therein will provide a limb for the staple to be formed. At this precise instant/,the shank l1 of the detail N (Figs. e7, 33, 35, 36 and 1S) is forced downward by the groove g2 (Fig. 3l & 3.,) the fiat spring 11 on the lower terminus of such vdetail bears upon the nippers m2 of the anvil block M (Fig. 46 che.) forces the same downward, holding the wire firmly in the mouth m" of such anvil block. The anti-friction roller b2 dle b on the'rear of the L-shaped cut-off bar VV (Figs. 1S-and 26) engages with the small cam D8 (Figs. 27 andi31) raising the same. The gro'oveb of such bar engages with the lug c5 of the cut-off tube c in the cut-olf block 'c (Figs. 26, 28 &c.,) lifts the saine, turns such tube in such block, forces the Wire in the'orifice otagainst the knife c2 angl severs the wire-see Fig. 40. It will be evi( ent that the extent of the movement of the feed arm T regulates the length of the wire fed through the anvil block M and .also the distance that the cut-off block c ac., will be drawn on the spin- I OO backward: or in other words, thelength ofthe wire fed in and cut od fromwhich a staple may be formed,-ihe eut o mechanism working with equal facility at 'whatever' point the lug c5 may be drawn lback to Within the groove h (Fig. 18) of the lower extremity of the L-shaped cut-off bar V. .and it wiltbe further seen that the extent of the movement of the feed arm T depends upon the distance of the finger Q', in the groove g2 of the disk g from the pin g in the center of such disk and on which such. disk turns; which position of the said finger in such groove is""'g"ov erned by the elevation of the face the bed-plate H, the cam D and their ent parts; which elevation the hand wheel W2 as hereinbefore shown. While the wire ww is` being fed into and. through the anvil block` M, theformer K (having the inclinedsnpport L between its sidebarsn and rn) together with the driver plate S, dependis governed by I simultaneously rise from the position indicated in Fig. 33 to that indicated in Fig. 35.

. the mouth of the anvil'block by the pressure of the detail N upon the nippers as abovede. scribed (Fig. 40). The former K (being'actuated by the anti-fricti`on roller K2 on the spindie K engaging with-the cam D in the groove q thereof) .now descends in advance of the driver I until the position is reached that is indicated 'in Fig. 36-the side bars 'n and fn.' passing down on each side of the anvil block M bending the ends ofV the wire protruding'r therefrom downward forming the staple (also Fig. 40) while the inclined support L bears againstthe mouth of the anvil block.- It will be seen that the limbs of the staple are now in the grooves os and o4 on the inside of thev side bars rt and n of the former K; (Figs. 33, 4l and 3G) that is to sayin the paths provided for the flanges p and p of the driver I (Figs. 3G and 1.2). The former K now remains in this position until the driver I has reached the limit of its descent. The driver I vnew@ Fig. Sti-(being actuated by theY anti-friction roller I3 on the spindle I2 of the driver head I' engaging with the cam D in the groove q" thereof, Figs. 31, 33,&c.,) begins its descent. vThe rst movement of the drivel' I from the position illustrated will force the anvil block M backward into the bed-plate II and against the coil spring m5; but the ends of the wire staple, being in the grooves ogvand o4 as aforesaid, the staple will remain when `the anvil blockis thus forced backward. The driver I continuing todescend pushes the staple down against the ledge L2 of the inclined'support L,

iin which position it will be held, because of the tension of the leaf spring L' until it is forced into the lip Z of the driver I as shown in Fig. 87, when it will be forced downward, as shown in Fig. 3S, until the driver I reaches the limit of its descentg--that is until the staple is completely driven (Fig. 39), the lip l operating to prevent the downward kinking of the staple shank while the staple is being driven. It will beseen that since the lip Z of the driver I so nearly surrounds the-top of the staple, the same being aided by the pressure of the inclined support L, while the grooves o2 and o4 guard three fourths of the circumference of the limbs, that the staple is prevented from kinkjng or breaking djown, andin consequence thereof much thicker work may be stapled than could otherwise be done. lVhen the staple is driven, the ends are clinched below by the action 'of the plunger X and pawis aa and act (Figs. 1-1, 15 1G &c.,) within the vertical double late Z', in the mannerhereinai'ter described. It will be understood that the various parts are returned to their first described positions byl a continuation of the movement of the actuating parts, aided by gravity and the springs indicated.
